Threats [top]

Major Threat(s): Deforestation and transformation of native forest to agricultural areas represents the main threat. Chytridiomycosis is also a threat to this species, as it is a high-elevation, stream-breeder, and declines due to the disease have already been detected amongst other species of this genus in this region.

Conservation Actions [top]

Conservation Actions: This species is not known to occur in any protected area, and protection of remaining cloud forest habitat in southern Chiapas is urgently needed. Given the possible threat of chytridiomycosis, the establishment of a captive-breeding programme might be necessary. This species is protected by Mexican law under the "Special Protection" category (Pr).
